Answer:
4a. 13
4b. -4
Step-by-step explanation:
2x-6/5 = 4 (Muti each side by 5)
2x-6 = 20
2x = 26 (Divide each side by 2)
x = 13
7- 2x/4 = 9
-2x/4 = 2 (Muti each side by 4)
-2x = 8 (Divide each side by -2)
x = -4
No, you can not separate:
ln ( 7 + x ) ≠ ln 7 + ln x
You can separate just if you have a logarithm of multiplication.
For example:
ln ( 7 · x ) = ln 7 + ln x
